Hi everyone,
I have recently picked up cubing again, after losing interest somewhere around 1990 (I am 30 now). I bought a EastSheen 4x4x4 and 5x5x5 last Christmas and was immediately hooked again. After this I have also bought a Rubiks 4x4x4 and 5x5x5 and a 3x3x3 DIY and a 2x2x2 EastSheen Extra Large. Some of you might have seen me at the Belgian Open.
I have noticed that I get my fastest times by "piramid solving". This means you start small, than go large and then go small again. For example:
Solve 5 2x2x2, 4 3x3x3, 3 4x4x4 and 2 5x5x5 as a warmup. After this I do a 5x5x5, 4x4x4, 3x3x3 and 2x2x2 and all these solves almost always are my fastest.
This is also the order I usually solve when I do a 2-3-4-5 (

I think this works so well because when you solve a 5x5x5 I use intuition for the centers, look-ahead when pairing up the edges and solve as a 3x3x3 with fewer moves because I can't use finger-tricks on my 5x5x5.
Than I start with a 4x4x4 and I don't see just one (obvious) way to do a couple of centers, but also a couple of ways to do these centers and prepare some more for easy positioning. Also pairing up the edges is easy because there are less. Finally solving as a 3x3x3 is faster because I can speed up a little and use some finger-tricks. Now if only I could avoid parities every time :angry:
Then the 3x3x3 seems easy, because I have just solved these bigger cubes. Because I am more confident, I always see a good way to do the cross and also looking ahead comes "naturally". Finally performing finger-tricks and longer sequences just seems easier than normal. The cube seems to move faster and more accurate.
The 2x2x2 finally is kind of like a nice dessert.
In short: more focussed, continually looking ahead, increasingly more fluent moves.
When I started doing 2-3-4-5 my times dropped from 13 minutes untill I reached 9 minutes. When I decided to do 5-4-3-2, my times immediately dropped to 8 minutes and I am approaching 7 minutes now.
